Outrage as RAF axes ageing fleet of eye-in-the-sky E-3 Sentry AWACS early warning planes TWO YEARS before their replacements are ready
The RAF is set to axe its eye-in-the-sky sentry planes two years before their replacements will be ready.
The airborne early warning and control system planes allow RAF pilots to detect enemy aircraft and provides situational awareness during operations.
But the E-3D sentry planes are set to be scrapped in December this year despite the fact their replacements are not ready.
The E-7 Wedgetail aircraft is expected to be in service with the RAF in December 2023 and is described by manufacturers Boeing as the 'world's most advanced, capable and reliable AWACS platform'.
RAF's E-3D sentry planes are set to be retired later this year but their replacements will not be ready until December 2023 meaning the UK will have to rely on NATO for cover
Until then, pilots will have to fly blind or rely on NATO's early-warning force, led by Luftwaffe's Maj Gen Jörg Lebert, according to the Sun.
Former armed forces minister Mark Francois, who raised the issue in a written parliamentary question, told the newspaper: 'It is unacceptable the RAF will lose its own eye in the sky for two years.'
'We should not be playing games with the air defence of the United Kingdom under any circumstances.'
The sentry planes, known as eye-in-the-sky, provide all-weather surveillance, command, control, and communications and are used by various air forces around the world.
A review in 2015 had set out plans to retain the E-3D planes but in March 2019, it was announced these would be replaced by the E-7 wedgetail sentry planes.
The Ministry of Defence announced it had awarded the £1.51billion contract to Boeing and initially ordered five E-7 planes, which will be able to detect multiple targets at sea or in the air over a considerable area for long periods of time.
Former armed forces minister Mark Francois , who raised the issue in a written parliamentary question, described the Ministry of Defence's decision as 'unacceptable'
The E-7A Wedgetail is manufactured by Boeing and will be ready in 2023. It will provide pilots with all-weather surveillance, command, control, and communications
However, in the 'Defence in a competitive age' document which was published in March this year, the MoD confirmed it had reduced the order to three planes.
The document stated: 'We will retire the E 3D Sentry in 2021, as part of the transition to the more modern and more capable fleet of three E 7A Wedgetail in 2023.
'The E 7A will transform our UK Airborne Early Warning and Control capability and the UK's contribution to NATO.'
The MoD said the decision reflects the fact that the aircraft have become increasingly difficult to maintain and costly to operate and that RAF personnel operate within NATO Airborne Early Warning & Control Force.
A spokesman told MailOnline: 'The retirement of the E3-D Sentry will allow reinvestment into our advanced E-7 Wedgetail fleet, which will provide a step-change in capability.
'As we transition between the two platforms, the NATO Airborne Early Warning & Control Force will provide cover if needed, supported by other RAF Intelligence Surveillance & Reconnaissance assets.'
How the Airborne Early Warning planes compare to each other
The E-3D
Powerplant: 4 CFM56-2A3 turbofans
Wingspan: 145ft 9ins
Length: 152ft
Cruise speed: 552mph
Range: 8,046km
Service ceiling: 43,000ft
Radar: Northrop Grumman APY-2
Crew: 5 flight crew / 12 mission crew
Capabilities: The E-3D's radar gathers information which is then processed by the mission crew and disseminated via a variety of data links and communication systems.
The sentry also has the capability to detect ships and can relay this information to maritime aircraft or allied vessels for further investigation.
Its electronic support measures equipment enables the E-3D to gather emissions from other radar systems and emitters.
This enhances the crew's understanding of the environment in which it is operating.
The E-7A Wedgetail
Powerplant: 2 CFM56-7B turbofans
Wingspan: 117ft 2ins
Length: 110ft
Cruise speed: 530mph
Range: 6,500km
Service ceiling: 41,000ft
Radar: Northrop Grumman MESA
Crew: 2 flight crew / 10 mission crew
Capabilities: The E-7A Wedgetail features advanced multi role electronically scanned array radar .
It also has 10 state-of-the-art mission crew consoles that are able to track airborne and maritime targets simultaneously.
The new L-band MESA radar is capable of simultaneously tracking 180 targets and conducting 24 intercepts.
It can cover four million square kilometres during a single 10 hour mission.
The E-7A also comes equipped with Electronic Warfare Self-Protection
